Read the following statements and choose the correct option :

Options

A. Respiration is purely a catabolic process
B. Reduction of food results in the release of energy
C. Chemical bond is broken down during respiration to release energy
D. Fungi can make their own food and derive the energy by respiration

Answer

To solve the question regarding the statements about cellular respiration, we will evaluate each statement one by one based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Cellular Respiration**:
- Cellular respiration is the process of breaking down organic compounds (like carbohydrates, proteins, and lipids) through oxidation to liberate energy, which is then used to synthesize ATP.

2. **Evaluating the Statements**:
- **Statement 1**: "Respiration is purely a catabolic process."
- **Analysis**: This statement is false. Cellular respiration is not purely catabolic; it is an amphibolic process, meaning it involves both catabolic (breaking down) and anabolic (building up) pathways.

- **Statement 2**: "Reduction of food results in the release of energy."
- **Analysis**: This statement is also false. In cellular respiration, organic compounds are oxidized, not reduced, to release energy. Therefore, the use of the word "reduction" makes this statement incorrect.

- **Statement 3**: "Chemical bonds are broken down during respiration to release energy."
- **Analysis**: This statement is true. During respiration, particularly the breakdown of C-H bonds, energy is released, which is then used to form ATP.

- **Statement 4**: "Fungi can make their own food and derive energy by respiration."
- **Analysis**: This statement is false. Fungi are heterotrophs, meaning they cannot make their own food; they obtain nutrients from other organisms and then derive energy through respiration.

3. **Conclusion**:
- Based on the evaluations, the only true statement is the third one: "Chemical bonds are broken down during respiration to release energy." Therefore, the correct option is the third statement.

### Final Answer:
The correct option is the third statement: "Chemical bonds are broken down during respiration to release energy."
